The Atmospheric Infra-Red Sounder (AIRS) Science Processing System (SPS) is a collection of computer programs, known as product generation executives (PGEs). The AIRS SPS PGEs are used for processing measurements received from the AIRS suite of infrared and microwave instruments orbiting the Earth onboard NASA’s Aqua spacecraft. Early stages of the AIRS SPS development were described in a prior NASA Tech Briefs article: “Initial Processing of Infrared Spectral Data” (npo-35243), Vol. 28, No. 11 (November 2004), page 39.
